DAVID 1v. IRWIN, OF'DETROIT, MICHIGAN .LWNING ISI G Ann Lownimvo nnvfcn Application filed February 4, 1928. I Serial No. 251,903.

My'in'vention relates to a new and useful improvement inan awning raising and lowering device adapted for use in the raising and lowering of awnings which are usually projected above and outwardly fromwindow openings and thelike. a a

It is an object of the present invention to provide a deviceof this class whereby the awning may be raised or lowered to any desired degree fromthe interior of the build ng.

It is another object of the invention to pro- It is another object of the invention to provide a device of this class which will be simple in structure, economical ofmanu'facture and highly efficient in use.

Other objects will appear hereinafter.

The invention consists in thecombination I and arrangement of parts hereinafter described and: claimed. g I The invention will be best understood by a reference to the accompanying drawings I which'form a part of this specification and in which @Fig; 1 is a side elevational View of the g g 1 the inner surface of the wall 7 Cords 30 and invention disposed in horizontal position 7 showing it applied.

Fig. 3' is a fragmentary view taken on line 33 of Fig. 2. v c Fig. 4 is an endelevational view of the invention disposed in vertical-form with a part broken away.

In the drawings I have; illustrated the invention used on [a structure having a wall 7 in which an opening-8 is formed for the re- ,ception of, the window 9, over the up or end 7 I i ofwhich is disposed an'awni'ng w 'ch is mounted in the usual'manner toswing down- I wardly and fold upwardly.

fixedly mounted upon the shaft 19. The gear '17 meshes with a gear integrally formed on one end of the roller or spool 21 which is imo'unted fixedly. on the shaft 22 which is rotatably disposed between and mounted on the legs of the U-shaped frame 11. A passage 23 is formed inone side of the roller 15, through which the cord or other flexible element can be projected and tied so that a rotating of the spool or roller 15 will effect a winding or unwinding of the cordjor flexible element thereon. A similar passage 24 is formed in the spool or roller 18 and a similar passage 25 is formed in the spool or roller 21. Fixedly mounted upon the shaft 19, interiorly of the building,-is a suitable crank 28 whereby this shaft may be rotated. Fixedly mounted upon the shaft 19 is a'ratchet wheel 27 en- 1 gageable with the dog 28 which is swingably mounted on the plate 29 which is mounted on 31 and 32 are fastened to separate parts of the awningin a well known manner, and each of these cords is secured to one of the spools indicated, the number of spools being determined by the number of cords used for raising or lowering'the awning. The number of cords will of course be determined to a large extent by the's'ize' and kind of awning with which used.

son interiorly of the building to place the crank 26 on the 'rod 19, and by means of the set'screw .33 bind the same thereon A rotation of the rod 19 will effect the desired'raising or loweringof the awning as the case may be.

As shown in Fig. 1 the device may be disposed in a horizontal position which may be inserted in some locations and on certain In Fig. 4 I have illustrated that the device may be used equally well in avertically' extended'position. In. order to accommodate the device for use in a vertically extended position, the frame is made U-shaped and the' connecting rod 12 and the roller 13 are of a less diameter than the width of the frame so that no interference is had with the cords when passing to or from the rollers or spools upon which wound or unwound.

The device is one which lends itself-to: a

I compact structurewhile at thesan e time affording an economical-method of manufacturing a durable device of this kind 7 While I have illustrated and described the preferred form of my'invention, I do not wish to 'limitmyself to the precise detailstof structure shown but desire to avail myself of such variations and modifications as come within fee yonv the inner endof said shaft for rotating the scope ofthe appendedclaims.

5. A device of the class described adapted for mounting on the exterior surface of a building wall comprising: a U-shaped frame;

a plurality of rollersrotatably mounted in said'frame; a shaft projected through one'of said rollers and through said wall, said shaft being rotatable in unison with said-roller; a' gear carried 'by each" of said rollers meshing with a gear on the adjacent roller; a crank on 1 the inner end of said shaft for rotating the samefa rod connecting the legs of said frame at their ends; and a sleeve rotatably mounted onsaid rod between said legs.

In testimony, whereof I have signed the foregomg speclfication.

Having thus described my inventionwhat I claim as new and desire to secure by Letters Patentis: V I 4 r 1.
